About us

František Macho, founder of X Shift Gearboxes, is a Czech entrepreneur and mechanical engineering expert who specializes in the development and production of racing gearboxes. In 1999, he managed to enter the racing world and started designing and manufacturing gearboxes and differentials for racing cars that met the high demands for quality, shifting speed, durability and reliability.

In 2002, he co-founded KAPS Transmissions, which established itself as a major manufacturer of racing transmissions. In 2012, he founded CNC MACHO Ltd., which focused on manufacturing transmissions for Subaru, Mitsubishi, Porsche and Nissan for KAPS. After disagreements with his partners, in 2018 he decided to continue under his own brand, X Shift Gearboxes, which specialises in the development and manufacture of sequential gearboxes and accessories for various automotive brands including Subaru, Mitsubishi, Porsche and Toyota.

Thanks to his expertise, experience and hard work, X Shift Gearboxes has established itself as a leading manufacturer of racing gearboxes that are used by racers around the world. The company focuses on continuous development and innovation to meet the growing demands of modern motorsport. The company currently has its own development centre, production hall, assembly workshop, warehouses and offices.

To achieve the highest quality of our products, we subject them to detailed inspection. Some of the controlling processes are as folows:

• Surface cracks detection
• Teeth profile inspection – Klingelnberg P100
• Hardness of teeth
• Effective case depth
• Microstructure of case depth
• Report of heat treatment process

In order to analyze complex geometry, we use special CNC 3D Coordinate Measuring Machine by Mitutoyo, that is able to scan the component’s most critic features with micrometer accuracy.

Heat treatment is very key step in production process, that gives the material required mechanical properties.

Modifying the physical, chemical and metallurgical properties of the part can optimize functionality and even extend the life of the part. Different methods of heat treatment can improve both surface and core hardness, boost machinability, enhance ductility and strength, minimize distortions and reduce wear and tear.

Some heat treatment processes target the whole part, while others may be directed at certain parts of the components, such as the teeth on the gear. Hence, depending on the requirements of specific gear application, different types of heat treatment may be utilized.
